Let’s move into more fraction work this week with MA.7.NSO.2.2!
How can we support students in learning this concept?
Before students see this problem:
Rational numbers are at the heart of all grade 7 learning. Have students spend some time practicing with integer operations and order of operations to review prior learning.
Small group rotations may help target individual student needs, such as assisting students who are still struggling with adding, subtracting, or dividing fractions. Look back at our problems from grades 4-6 to help support students struggling with fractions.
Give students this problem:
Have students spend 2-3 minutes working on the problem individually; encourage them to star expressions they are unsure of (such as where to start)
Have students work with a partner to compare answers and help each other with expressions they may have missed.
Ask students to share their answers with the whole group. Ask students to justify their answers; if students identify an incorrect expression, ask other students to justify why that expression is not equivalent to -14.
After students see this problem:
Ask pairs of students to come up with a different expression that is also equivalent to -14. Have them record their expression and work to show it is equivalent to -14 on a slip of paper to hand in.
Encourage students to use multiple operations and/or fractions and decimals.
Collect student expressions and display a few on the board for the class to see. Have students spend 2-3 minutes on the expressions to justify whether they are equivalent to -14.
If an expression is not equivalent to -14, ask students to discuss what might have gone wrong in their thinking. Encourage them to fix the expression so that it is equivalent to -14.
